I do appreciate all that, and the advantages and disadvantages of bothcorded and cordless tools, but cost is the limitation as well as durability. The boatyard manager offered to let me off 3 months yard rental, I owe money to extended family and people at work even donated me cans of food.
I thought the Hitachi drill I bought above for £25 had an adjustable torque control. If such a drill has not been manufactured, then ok, I will try to borrow a cordless driver, and the rest by hand. Just be careful not to break it!
I am interested in the question for its own sake also. It surprises me if there are none from when cordless tools were less popular. If no-one has heard of such a thing, I also wonder why.
